	<h3>Function Parameter Descriptions</h3>
	<div class="desc">
	<h4><b>targetNode</b><span>JSON</span></h4>
	<p>JSON data object of the node which will be target.</p>
	<p class="highlight_red">If copy the node to root node, please set the 'targetNode' to null.</p>
	<p class="highlight_red">Please ensure that this data object is an internal node data object in zTree.</p>
	<h4 class="topLine"><b>treeNode</b><span>JSON</span></h4>
	<p>JSON data object of the node which will be copied.</p>
	<p class="highlight_red">Please ensure that this data object is an internal node data object in zTree.</p>
	<h4 class="topLine"><b>moveType</b><span>String</span></h4>
	<p>Copied to the target node's relative position.</p>
	<p class="highlight_red">"inner" means: to be taregetNode's child node.</p>
	<p class="highlight_red">"prev" means: to be taregetNode's previous sibling node.</p>
	<p class="highlight_red">"next" means: to be taregetNode's next sibling node.</p>
	<h4 class="topLine"><b>isSilent</b><span>Boolean</span></h4>
	<p>After copy the node, whether to automatically expand its parent node.</p>
	<p>isSilent = true means: don't expand its parent node.</p>
	<p>isSilent = false or omit this parameter means: expand its parent node.</p>
	<h4 class="topLine"><b>Return </b><span>JSON</span></h4>
	<p>return the new node in zTree</p>
	<p class="highlight_red">Note: the node data JSON object in the return value is not equal to the treeNode.</p>
